EYEGLASSES OR SPECTACLES.

SPECIFICATION forming part of Letters Patent No. 764,101, dated July 5, 1904.

Application filed December 31, 1903. Serial No. 187,301. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE E. APPLEGATE, of Trenton, in the State of New Jersey, have invented certain new and useful Improvements in Eyeglasses or Spectacles, whereof the following is a specification, reference being had to the accompanying drawings.

My invention is particularly applicable to frameless or rimless lenses, and provides peculiar attaching means to maintain such lenses in proper relation with clamps or other frame members.

As herein after described, my invention comprises a lens of the class specified having an attaching member, preferably of metal, permanentl y secured in stationary position in a recess in the lens and comprising aprojection which may be engaged in screw-threaded or riveted connection with a frame member without removal from the lens.

My improvements also provide a frame member arranged to engage such lens-attaching means regardless of such slight variations in the location of said stationary projection with respect to the edge of the lens as are incident to the rapid manufacture of such lenses.

My invention comprehends the various novel featur es of construction and arrangement hereinafter more definitely specified and claimed.

In the drawings, Figure I is is a face view of a lens provided with attaching means comprising a screw-threaded bolt secured in stationary relation with the lens and nuts fitted to said bolt. Fig. II is a sectional view taken on the line II II in Fig. I. Fig. III is a sectional view of a lens, showing modified means for securinga projecting attaching member in stationary position. Fig. IV is a perspective view showing a fragment of a lens and a clampconnected therewith by the attaching means shown in Fig. I. V isa perspective view of a fragment of a lens provided with a peripheral notch to engage a projection on a frame member. Fig. VI shows a modified form of attaching means and aframe member adapted for engagement therewith.

Referring to Figs. I, II, and III, the lens 1 is provided with a recess or aperture 2, in

which the screw-bolt 3 is permanently secured by the bushing 4, (which may be of cement,) and said bolt is provided with nuts 5 on its opposite ends to engage similar opposite straps of a clamp or other frame member.

The lens 7 (shown in Fig. III) is provided with the screw-bolt 8, which is fixed in the aperture 10 by means ofthe bushing 11, which latter may be of metal or other material capable of being swaged to form shoulders 12 upon the opposite sides of the lens at right angles to the axis of said bolt 8, so that the straps of the frame member engaged with said bolt come in contact with the opposed parallel surfaces of said shoulders 12 instead of in contact with the converging opposite faces of said lens 7, thus insuringa more uniform distribution of the clamping pressure on the frame member.

Referring to Fig. IV, the lens-clamp 14 comprises the flanged seat 15 to receive the bridge and nose-guard members. Said seat is connected by the shank 17 with the plate which comprises the wings 18, arranged to engage the edge of the lens 1, and straps 20, extending on opposite sides of the lens. Said straps engage the bolt 3 and are secured by nuts 5. The similar straps 20 (only one of which is indicated in Fig. IV) are bifurcated by similar slots or notches 21, which terminate adjacent to the wing members '18 and extend to the free ends of the straps, being of such extent as to register with the projecting attaching member 3 regardless of such variations in the distance of said member from the edge of the lens as are incident to rapid production of such lenses.

Referring to Fig. V, the lens 23 is provided with attaching means comprising the projecting stud 2 1, permanently secured in stationary position in the bushing 25 in the recess or notch 26 in said lens. Said notch is adapted to receive and engage the lug 27, projecting from the lens-clamp or other frame member, which latter is secured upon said lens by upsetting the projecting ends of said member 24 to form rivet-heads engaged therewith.

Referring to Fig. VI, the lens 28 is provided with attaching means comprising the member 29, having serrated edges adapted to fit anywherein the series of corresponding serrations 30 along the frame member b1, so that the latter may. be applied with its wings 32 in contact with the edge of the lens 28 regardless of slight variations in the location of said member 29 with respect to the edge of the lens.

I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention.

I claim- 1. An eyeglass or spectacle lens, provided with an attaching member seated in an aperture in said lens and projecting from one side thereof, and arranged to extend through a frame member; and, means permanently securing said member in said lens, substantially as set forth.

2.
